Using ValueExpression's in a validator tag

I have a component on which I need 2 validations performed. I want to execute the required validator, based on a ValueExpression, and a custom validator I've written. The problem I'm running into is that the jsf validator tags have a disabled property and although the documentation states they accept a ValueExpression, they do not. So this led me to attempt adding an attribute to my own validator that would accept a ValueExpression. Unfortunately I am not having any luck. Here's my taglib.xml

So my questions are:
1. Is it possible to create a ValueExpression attribute on a custom validator tag? and
2. What do the validator property-handling methods look like?
